I'm making an over the table dust hood for my table saw. I've already made the run from the side of the saw to the blade, just pvc pipe and fittings and now need to make the hood. I'm using some 3/8 acrylic plastic from the scrap bin from a shop here in town. My problem is that I'm using a Diablo 10' blade from Freud and that thing spits dust from the back side of the blade like I've never seen. I rip a lot of wood that is 7" and better and have to turn the board over for the second cut which means sawdust is not only spitting out the back but out the front along the previously cut slot. So it looks like my hood will end up being about 14" long to try and catch it all. I'm going to try and mount the intake further toward the back of the hood hoping to catch more of the dust off the back of the blade. Now I'm wondering if I need to put some baffles in the hood to try and direct the flow. The hood will be 14" long by 2 1/2 wide by 3" high. If I had a 4" collection system I'm sure it would work better and not need anything but 14" is awfully long for a hood. Unfortunately that's about what I'm going to need.... I think!
Does anyone have any suggestions or ideas, or have you built your own hoods
